The official synopsis for Legends of Tomorrow is as follows: “Having seen the future, one he will desperately try to prevent from happening, time-traveling rogue Rip Hunter (Darvill) is tasked with assembling a disparate group of both heroes and villains to confront an unstoppable threat—one in which not only is the planet at stake, but all of time itself. Can this ragtag team defeat an immortal threat unlike anything they have ever known?”
